The hollow cylinder is adaptarably connected partsis easily taken apart after 55 use insuring effective cleansing and sterilizlng. The internal parts may be changed or replaced in the introduction of various antiseptic powders. This procedure is of particular importance as it aids in keeping different type powders free from self contamination. The use of the slotted cage I4 with the transparent ampule 26 by which the powder level is made visible to the operator has been found advantageous. The elimination of the necessity of transferring the powder from the ampule into the device simplifies the loading procedure and insures the sterile condition of the powder.

We have found that the narrow projecting tube 23 with the small lateral holes or perforations, that is inserted into the ampule with the powder, prevents the powder from being blown out all at once and insures a gradual, slow, even distribution of a fine stream of pulverized powder in spray form all over the interior of the vagina.

While we have illustrated our invention showing certain preferred embodiments thereof, it will be understood that our invention is not necessarily limited thereto. All modifications. coming within the true spirit and scope of our invention are intended to be covered by the claims appended hereto.

We claim:

1. In a separable powder insulator of the class described, the combination of a hollow cylinder having an end wall, a central external nipple on said end wall, and an annular seat on the inner side of said end wall encircling the bore of said nipple, the other end of said cylinder being open; an elongated cap having a screw thread connection with the open end of said cylinder and forming a longitudinal extension of the latter, said cap having an end wall formed with a central hole,

and an annular seat on the inner side of said last named end wall encircling said hole, a powder ampule housed within said cylinder and cap, said ampule formed with open ends forced into snug contact with said annular seats by screwing said cap inwardly of said cylinder, a tube mounted in said hole and projecting into said ampule, said tube having holes in its walls, an air forcing device connected to said nipple, and a discharge nozzle secured to the end wall of said cap with its bore in line with the bore of said tube.

2. In a separable powder insuillator of the class described, the combination of a hollow cylinder having a longitudinal sight slot in its longitudinal wall, an end wall, a central external nipple on said end wall, and an annular compressible seat on the inner side of said end wall encircling the bore of said nipple, the other end of said cylinder being open; an elongated cap screwed onto the open end of said cylinder and forming a longitudinal extension of the latter, said cap having an end wall formed with a central tapped hole and an annular compressible seat on the inner side of said last named end wall encircling said hole, a glass ampule for containing powder housed within said cylinder and cap, said ampule formed with open ends forced into air tight contact with said compressible seats by screwing said cap hard onto said cylinder, a tube at one end screwed into said tapped hole and projecting into said ampule approximately the full length of the latter, said tube having a closed free end and holes in its side walls, an air forcing device connected to said nipple, and a discharge nozzle detachably secured to the end wall of said cap with its bore in line with the bore of said tube.
